T0 all fro/0m it may concern.'

Be it known that I, JOHN M. RoHLFINo, residing at St. Louis, Missouri, and being a citizen of the United States, have invented certain new and useful Improvements in Bunks or Body-Holsters, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and to use the same, reference being had to the accompanying drawings, which illustrate the preferred form of the invention, though it .is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modifications thereof will occur to persons skilled in the art.

In said drawings: Figure l is a plan view of the improved bunk, part of one end being broken away as it is a duplicate of that illustrated; Fig. 2 is a longitudinal vertical sectional view taken on the planes indicated by the lines 2 2 of Fig. l; Fig. 3 is an end view of the parts shown in Fig. l.

The object of the invention is to produce a bunk or body bolster especially useful in log car construction in which the side longitudinally extending members thereof are formed from commercially rolled flanged sections of metal and preferably of channel shape as rolled, which sections are bent longitudinally of their web portions, leaving the angular flanges in their original posit-ion and angle with reference to the web portions immediately adjacent thereto so that when two of such re-formed sections are brought into juxtaposition as shown in the drawings they will provide a plurality of channels, one of which is relatively narrow and deep, and an outer channel which is wider and preferably more shallow, the wider channel being at thetop as illustrated, thereby providing working space for operating mechanism within the narrow and wide channels, with vertical or relatively vertical rails at each side of the same, upon which rails the logs may rest and roll in loading or unloading the car. To secure these re-formed sections together and t o hold them in operative position with their webs F in both vertical and horizontal position, as shown in the end elevational View of Fig. 3, I secure to each end thereof the U-shaped castings H which are angle shaped in cross section with one leg of each angle Specification of Iietters Patent.

section riveted to the lower flanges G and the lower web portions of the channels, and I also connect the said bottom flanges of the channels near the middle of their length by riveting thereto the center bearing casting I so that the end castings and center bearing castings connect said channel sections in such position that the lower portions B of their webs are vertical, and the upper portions B of such webs are relatively horizontal.

Upstanding from the horizontal portions of the webs are the top flanges S which are substantially vertical. Connecting the horizontal portions of such webs I use a tie plate l wiich is riveted to the webs vertical flanges vertically above the center bearing casting. The width of the bunk or bolster' may vary and the re-formed channels may be spaced apart any suitable distance but I prefer that the inturned lower 'flanges (if shall be slightly separated as shown in Fig. l, so as to leave a clear space 2 between the contiguous edges of such flanges.

As will be noted in the accompanying drawing, the vertical webs of the channels F are imperforate while the horizontal portions B of such webs are perforated at suitable intervals as at 3 to receive suitable stops (not shown) adapted to serve as checks to hold logs in position upon the rails or vertical flanges S As will be noted from an inspection of the d viawings, the construction provides three tracks or runways in different vertical planes: The first comprises the lower flanges G G at the bottom; the next higher track or runway comprises the horizontal portions B B of the webs F, and the upper track or runway comprises the upper edges of the vertical flanges S S and each trackway may be utilized without interfering with suitablematerial or mechanism, adapted for the purpose described, occupying the other trackways.

That I claim is:

l. In a car underframe, a transversely disposed supporting member comprising the combination of spaced channel beams having their webs bent longitudinally for disposing their upper flanges in upstanding position, and means connecting said beams.

2. In a car underframe, a transversely disposed support-ing member comprising the combination of channel beams having their between the.

channels opening toward each other, and having their webs bent longitudinally to positions disposing their upper flanges in upstanding condition, and means connecting said beams. i

3. In a car underframe, a transverselydisposed supporting member comprising the combination of channel beams, and means connecting the same, the webs of each channel beam being bent longitudinally for positioning the upper portion thereof; in a horizontal plane, providing a tread"v lth the upper flange of the beam upsta'nding therefrom. f

l. In a loggingbunk, a flanged beam bent longitudinally intermediate its width for forming a tread of' a portion of the web and disposing a flange upstanding therefrom.

5. In a logging bunk, the combination comprising re-formed rolled channels forming runways in three separate planes.

6. In a bunk, the combination of a pair of flanged beams bent longitudinally intermediate their flanges for forming treads hav- `ing upstanding flanges, and a plate intermediate the length of the beams connecting said treads and end plates connecting the beams.

7. In a bunk, the combination of flanged beams each bent longitudinally intermediate its widthl'or forming a tread having an upstanding flange, and end plates disposed outside of and connecting said beams.

8. In a bunk, the combination of flanged beams bent longitudinally intermediate their width, and means connecting said beams.

9. In a bunk, the combination of flanged beams each bent longitudinally intermediate its width, top and bottom plates intermediate the length of and connecting said beams, and end plates connecting the beams and formed to leave an open passage way between the beams.

10. In a car underf'rame, a transversely extending member comprising the combinavtion of a pair of flanged beams, one of the flanges of each beam extending toward the other beam, and each of the beams being bent outwardly longitudinally intermediate its 'width, forming an outstanding tread having an upstanding flange, and means connecting said beams.

11. In a car underframe, a transversely extending member comprising the combination of' a pair of flanged beams, one of the flanges of each beam extending toward the other beam, and each of the beams being bent outwardly longitudinally intermediate its width, forming an outstanding tread having an upstanding flange, and ai U shaped plate disposed outside of and connecting said beams.

12. In a car underframe, a transversely extending member comprising the combination of a pair of flanged beams, one of the flanges of each beam extending toward the other beam, and each of the beams being bent outwardly longitudinally intermediate its web, forming an outstanding tread having an upstanding flange, and a U shape plate at each end of the beams disposed outside of and connecting t-he beams.

13. In a car underframe, a transversely extending member comprising the combination of a pair of channel beams, each having its web bent longitudinally outwardly intermediate its width, forming a tread, and U shape plates inclosing and connecting said beams, and extending upwardly tothe treads thereof.

lll. In combination, a pair of re-formedv rolled flanged sections forming a narrow channel and a wide-r channel in' dierent planes and of dierent widths, and a tie plate connecting the webs of said channels.

15. In combination, a plurality of reformed rolled channels having both vertical and horizontal web portions and connected webs. p

16. In combination, a. plurality of reformed rolled channels having both vertical and horizontal web portions and connected lower flanges with vertical upper flanges.

17.\ In a car structure, a supporting member comprising rolled flanged members reformed to provide horizontal and vert-ical flanges and intermediate web portions which are angularly disposed to provide a horizontal trackway.

18. In a car structure, a supporting member comprising rolled flanged members, the webs of which are bent at right angles longitudinally, thereby forming spaced tracks; a tie plate connecting Vsaid webs, and a center bearing member connecting the flanges of said rolled members.

19. In a car structure, a supporting member comprising rolled flanged members, theA webs of which are bent at right angles longitudinally, thereby forming spaced tracks; a tie plate connecting said webs, unitary connecting means for uniting the ends of said rolled members and secured to the flanges and webs thereof.

In witness whereof I have hereunto set myhand in the presence of two witnesses.
